【摘要】 随着旅游产业发展的不断深入,城市作为旅游活动的主要载体,备受关注,成为旅游研究的重要方面,城市旅游空间结构日益成为城市旅游研究的热点问题,但对其研究的方法论尚未完全建立起来,研究以定性描述为主,缺乏必要的定量研究。本文尝试运用旅游景点可达性方法来定量的研究城市旅游空间结构,开发了基于最短时间路径选择算法的旅游景点可达性计算与分析信息系统,并基于南京市区的公路路网结构,对南京市区旅游景点可达性做了实证研究。通过系统计算生成了景点可达性的分值扩散图,时间等值线图、旅游景点服务范围图和以乡镇为基本计算单元的景点可达性图。通过对生成图表的分析,笔者发现:南京市区旅游景点整体可达性较好,80.59%的区域景点可达性在40min之内,但其内部差异也比较明显,中心主城区景点可达性较好,外围地区特别是边界地区景点可达性较差,最差地区为103min39s,通过对乡镇为基本计算单元的整体景点可达性的等级分析,发现南京市区景点可达性在地域分布上呈现以主城区为中心的圈层空间结构。在上述分析的基础上,将南京市区分为主城区、近郊区、远郊区三个区域,根据三个地区各自特点制定了相应的景点可达性优化目标,并给出了优化措施:主城区的优化途径是路网结构优化为主,旅游景点建设为辅;郊区的优化路径是旅游景点建设为主,路网结构优化为辅;远郊区是旅游景点建设和路网结构优化并重。本文共分为六章,第一、二章介绍了研究的背景、意义、方法、框架,并回顾了前人的研究成果,第三章在评析前人可达性研究方法的基础上,构建了基于最短时间路径选择算法的旅游景点可达性计算与分析信息系统,第四章以南京市区为研究区域,深入分析了南京市区旅游景点可达性情况,第五章在上述分析的基础上,探讨了南京市区旅游景点可达性的优化方案,第六章对全文做了总结。更多还原

【Abstract】 With the rapid development of tourism industry and living pace, residences increasingly improved its requirements of tour convenience. This paper applied accessibility to tourism study and broadened its research arena to explore scenic spots accessibility calculation and analysis information system which was based on minimal pass-time oriented optimal route arithmetic. Based on the Nanjing road networks, this paper undertook empirical research in terms of accessibility of scenic spots in Nanjing downtown areas so as to generate mark Diffusing figure, Time contour, Service scope figures for scenic spots as well as Rank distributing figures of accessibility.Though analyzing these figures and charts, the author found that the accessibility of Nanjing scenic spots as a whole is satisfactory, with over 88% regional accessibility maintaining less 45 minutes. However, the inner difference gap is obvious, for the fact that the accessibility of downtown areas is much more superior to the outermost boundary which has reached 103min39s to some extent. Though ranking analysis of the whole accessibility in terms of villages and towns administration unit, a Circling-layering spatial structure focused by downtown area in terms of the regional distributing accessibility could be obtainedDue to the disequilibrium of inner-regional accessibility, the paper suggested that government should quicken the pace to build the peripheral scenic spots, to optimize its spatial distribution, and to perfect the planning of scenic spots in recreational belt around metropolis, and the construction priority should be given to Liuhe, Pukou and Jiangning districts of Nanjing for the consideration of poor accessibility.更多还原
